Dab tsi yog qhov txawv ntawm Cold Plated Pipes thiab Kub Plated Pipes

Muaj ob lub ntsiab ntawm cov kav dej galvanized, ib qho yog kub-dip galvanized yeeb nkab thiab lwm yam yog txias dip galvanized yeeb nkab. Ob leeg yog cov kav dej galvanized, tab sis lawv cov ntsiab lus tseem ceeb sib txawv, yog li kuj muaj qee qhov sib txawv. Qhov sib txawv ntawm cov kav dej txias galvanized thiab cov kav dej kub-dip galvanized feem ntau yog tshwm sim hauv cov hauv qab no:
1. Qhov sib txawv ntawm cov qauv tsim khoom
Kub dip galvanizing yog ib txoj kev ntawm galvanizing ib lub workpiece los ntawm immersing nws nyob rau hauv ib tug molten zinc tov rau ib lub sij hawm ntawm lub sij hawm tom qab degreasing, pickling, dipping, thiab ziab, siv cov tshuaj tiv thaiv ntawm cov hlau matrix thiab molten hlau los tsim ib tug galvanized txheej. ; Txias galvanizing, tseem hu ua electroplating galvanizing, ua haujlwm los ntawm kev siv cov khoom siv electrolytic kom tshem tawm cov roj thiab cov kua qaub ntawm lub workpiece, muab tso rau hauv ib qho kev daws teeb meem ntawm zinc ntsev, thiab txuas cov electrode tsis zoo ntawm cov khoom siv electrolytic; Muab ib lub phaj zinc tso rau ntawm qhov chaw ua haujlwm thiab txuas mus rau qhov zoo electrode ntawm cov khoom siv electrolysis. Txuas cov khoom siv hluav taws xob thiab siv cov kev taw qhia ntawm qhov tam sim no los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode kom tso ib txheej zinc ntawm lub workpiece.
2. Qhov sib txawv ntawm cov yam ntxwv ua haujlwm
(1) Cold galvanized yeeb nkab: galvanized txheej ntawm txias galvanized yeeb nkab yog tuab, nrog zoo thiab zoo crystallization thiab tsis muaj pores, yog li nws muaj corrosion kuj zoo; Tsis tas li ntawd, zinc txheej tau los ntawm txias plating yog cov ntshiab thiab corrodes maj mam nyob rau hauv acid, alkali thiab lwm yam pos huab, uas yuav zoo tiv thaiv cov hlau substrate. Lwm tus yam ntxwv ntawm txias galvanizing yog cov zinc txheej yog passivated nrog chromic acid los ua dawb, xim, tub rog ntsuab, thiab lwm yam, uas yog zoo nkauj thiab muaj ib co zoo nkauj tus nqi.
(2) kub dip galvanized steel yeeb nkab: kub galvanized steel txheej thiab tuab cov hlau substrate los ntawm corrosion, thiab muaj qhov zoo tshaj plaws los tiv thaiv corrosion; Vim nws txoj kev sib raug zoo thiab kev sib koom ua ke ntawm zinc thiab hlau, cov kav dej kub-dip galvanized muaj zog hnav tsis kam; Vim yog qhov zoo tshaj plaws ductility ntawm zinc, nws cov alloy txheej adheres rau cov hlau substrate, cia kub-dip plated qhov chaw los ntawm ntau yam txheej txheem xws li txias stamping, dov, kos duab, thiab dabtsi yog khoov yam tsis muaj kev puas tsuaj rau txheej; Tom qab kub-dip galvanizing ntawm steel structural Cheebtsam, nws yog sib npaug rau ib tug annealing kev kho mob, uas yuav ua tau zoo txhim kho cov neeg kho tshuab cov khoom ntawm steel substrate, tshem tawm cov kev nyuaj siab thaum lub sij hawm tsim thiab welding ntawm steel Cheebtsam, thiab pab txhawb txoj kev tig ntawm steel structural. cov khoom.
3. Qhov sib txawv ntawm daim ntawv thov
Daim ntawv thov ntawm cov kav dej kub-dip galvanized kuj tau nthuav dav nrog kev txhim kho kev lag luam thiab kev ua liaj ua teb. Yog li ntawd, cov kav dej kub-dip galvanized tau siv dav hauv kev lag luam (xws li cov cuab yeej siv tshuaj, kev ua roj av, kev tshawb nrhiav hauv hiav txwv, cov qauv hlau, kev xa hluav taws xob, kev tsim nkoj, thiab lwm yam), kev ua liaj ua teb (xws li cov dej txau dej, chav cua sov), kev tsim kho (xws li. xws li dej thiab roj tsheb thauj mus los, xaim hlua, scaffolding, tsev, thiab lwm yam), txuas hniav, tsheb thauj mus los, thiab lwm yam.
Vim muaj qee qhov tsis xws luag, cov kav dej txias galvanized tau raug txwv tsis pub siv los ua cov kav dej thiab cov pa roj, thiab tau pib tshem tawm ntawm kev thauj mus los ntawm cov dej. Txawm li cas los xij, cov kav dej txias galvanized tseem siv nyob rau hauv qee cov dej tua hluav taws thiab cov qauv zoo tib yam vim tias lawv cov vuam ua tau zoo heev.
